What type of injury does a "night stick fracture" typically refer to?

A "night stick fracture" specifically refers to an injury characterized by an isolated fracture of the ulna. This type of fracture is commonly associated with a defensive injury, often occurring when an individual raises their arm to protect themselves from an attack, such as a strike with a blunt weapon. The ulna, being the longer of the two bones in the forearm that runs parallel to the radius, is particularly vulnerable in these scenarios.

In this context, a night stick fracture typically results from direct impact or stress applied to the ulna without accompanying damage to the radius. Understanding this injury is important for orthopedic technologists, as it helps inform treatment plans and the method of immobilization required for healing. Recognizing the mechanism of injury also aids in assessing potential complications or associated injuries in a clinical setting.
